The purpose of this work was to determine the causes of cancellation of elective surgical operations in a major pediatric surgery department in Senegal. Patients and methods: It was a prospective and descriptive study of 278 patients scheduled during a period of 13 weeks. The study took place between April 3<sup>rd</sup>, 2017, and January 31<sup>st</sup>, 2018. Mean age was 2.9 years with extremes of 3 days and 15 years. The age group of 29 days to 30 months was the most represented (62.2%). Sex ratio was 1.41. Causes of cancellation were categorized into administrative and organizational causes, patient-related causes and staff-related causes. Results: Cancellation rate was 29.4%. Patient-related causes were most common (51.2%). Upper Respiratory tract infection (URTI) was commonest reason within this category (57.5%). Organizational causes (28.1%) came second and were mainly represented by the unavailability of the operating room (60.8%) related to breakdowns of anesthesia equipment. Finally, staff-related causes (20.7%) were due for most to the unavailability of the anesthesiologist (12 cases/17). Conclusion: Majority of causes that led to cancellation of elective surgical operations in our Pediatric surgery department are related to intercurrent illnesses affecting the patient, in particular URTI.展开更多

With the assistance of robotic surgical systems, maxillofacial surgery is performed with less blood loss, fewer complications, shorter hospitalization and better cosmetic results than standard open surgery.However, the application of robotic surgery techniques to the treatment of head and neck diseases remains in an experimental stage, and the long-lasting effects on surgical morbidity, oncologic control and quality of life are yet to be established. More well-designed studies are needed before this approach can be recommended as a standard treatment paradigm. Nonetheless,robotic surgical systems will inevitably be extended to maxillofacial surgery. This article reviews the current clinical applications of robotic surgery in the head and neck region and highlights the benefits and limitations of current robotic surgical systems.展开更多

We compared surgical and non-surgical and education among training programs and expected surgical comfort level with pelvic reconstructive procedures from the perspective of the fellow and program director. An online survey was distributed to program directors and fellows from the 39 accredited FPMRS fellowships at the time (2010). Domains evaluated in the survey were academic education requirements;surgical approaches to prolapse and to incontinence;other surgical procedures;and research and publication expectations. In total, forty fellows from 21 programs and directors from 27 programs. The most common surgical procedures performed for apical, anterior, and posterior prolapse were uterosacral ligament suspension, native tissue anterior colporrhaphy, and posterior colporrhaphy, respectively. Differences in perceived surgical comfort level were seen for coccygeus suspension, graftreinforced posterior colporrhaphy, rectus fascial sling, urethral bulking agent, cystoscopic ureteral stent placement and bowel repair. A greater proportion of program directors reported that fellows would be comfortable performing these procedures upon graduation than the proportion reported by the fellows themselves. Differences exist in FPMRS training nationwide, however, responding fellows appeared to be trained in multiple approaches to prolapse repair. Differences were seen in surgical comfort level as perceived by fellows and program directors.展开更多

METHODS: A thorough search of electronic databases MEDLINE, Embase, Pubmed and Cochrane Library, from 1997 up to January 2011 was performed. An analysis was carried out, pooling the effects of outcomes of 4241 patients enrolled in 80 retrospective studies. For comparisons across studies, each reporting on only one endoscopic method, we used a random effects meta-regression of the log-odds of the outcome of treatment in each study. "Neural networks" as a data mining technique was employed in order to establish a prediction model of lymph node status in superficial submucosal esophageal carcinoma. Another data mining technique, the "feature selection and root cause analysis", was used to identify the most impor-tant predictors of local recurrence and metachronous cancer development in endoscopically resected patients, and lymph node positivity in squamous carcinoma (SCC) and adenocarcinoma (ADC) separately in surgically resected patients. RESULTS: Endoscopically resected patients: Low grade dysplasia was observed in 4% of patients, high grade dysplasia in 14.6%, carcinoma in situ in 19%, mucosal cancer in 54%, and submucosal cancer in 16% of patients. There were no significant differences between endoscopic mucosal resection and endoscopic submucosal dissection (ESD) for the following parameters: complications, patients submitted to surgery, positive margins, lymph node positivity, local recurrence and metachronous cancer. With regard to piecemeal resection, ESD performed better since the number of cases was significantly less [coefficient: -7.709438, 95%CI: (-11.03803, -4.380844), P < 0.001]; hence local recurrence rates were significantly lower [coefficient: -4.033528, 95%CI: (-6.151498, -1.915559),P < 0.01]. A higher rate of esophageal stenosis was observed following ESD [coefficient: 7.322266, 95%CI: (3.810146, 10.83439), P < 0.001]. A significantly greater number of SCC patients were submitted to surgery (log-odds, ADC: -2.1206 ± 0.6249 vs SCC: 4.1356 ± 0.4038, P < 0.05). The odds for re-classification of tumor stage after endoscopic resection were 53% and 39% for ADC and SCC, respectively. Local tumor recurrence was best predicted by grade 3 differentiation and piecemeal resection, metachronous cancer development by the carcinoma in situ component, and lymph node positivity by lymphovascular invasion. With regard to surgically resected patients: Significant differences in patients with positive lymph nodes were observed between ADC and SCC [coefficient: 1.889569, 95%CI: (0.3945146, 3.384624), P<0.01). In contrast, lymphovascular and microvascular invasion and grade 3 patients between histologic types were comparable, the respective rank order of the predictors of lymph node positivity was: Grade 3, lymphovascular invasion (L+), microvascular invasion (V+), submucosal (Sm) 3 invasion, Sm2 invasion and Sm1 invasion. Histologic type (ADC/SCC) was not included in the model. The best predictors for SCC lymph node positivity were Sm3 invasion and (V+). For ADC, the most important predictor was (L+). CONCLUSION: Local tumor recurrence is predicted by grade 3, metachronous cancer by the carcinoma insitu component, and lymph node positivity by L+. T1b cancer should be treated with surgical resection.展开更多

Methods: 52 patients underwent Sono-Guided Endostripping and 52 patients had radiofrequency ablation with Celon Olympus device. They were followed for 3 months with physical examination and Doppler Sonography for possible complications and recanalization. Results: Recanalization rate was 11.5% in RFAs while it was 0.0% in the Endostripping group. There were no significant differences for other complications (hematoma, DVT, paresthesia) but pain, which had 1.21 and 3.15 VAS scores for RFA and Endostripping groups, respectively. Recanalization rate was more in RFA comparing with the Endostripping group (11.5% vs. 0.0%,?P?< 0.013). RFA was more expensive. Conclusion: Sono-Guided Endostripping is a safe and cost-effective method (due to no need for using RFA probe);however, the patient must be admitted to the hospital and take appropriate anesthesia. Cosmetic result of the technique is fairly comparable with RFA scars in the thigh and leg.展开更多
